5-10 Power-up and Testing

To check function of the Fluid Pressure Regulator and Gauge:

1. Turn the Reservoir Air Pressure Pneumatic Switch to the ON

(l) position (Figure 5-9).

2. Locate the Fluid Pressure Regulator adjustment knob underneath the left side of the

front hood.

3. Unlock the knob by pulling it downward.

4. Rotate the Fluid Pressure Regulator adjustment knob counterclockwise until the Fluid

Pressure Gauge registers 0 psi.

5. Rotate the knob clockwise until the Fluid Pressure Gauge registers 60 psi (413 kPa).

TIP For accurate pressure adjustment, lower the pressure below the desired level and then

increase to the desired pressure.

6. Monitor the Fluid Pressure Gauge to make sure that pressure builds at a steady rate. Watch

for dropping pressure indicating an air leak.

! If there is an air leak, identify the source, shut off the facility air, and fix the leak before

proceeding.

7. Lock the knob by pushing it upward.
